twitter connection failed

Question

In Android,
Twitter connection failed. SSL is required?

My code was working perfectly and it is currently a live application. However, since 2014 it hasn't been working and I've heard that Twitter has applied https or using SSL concept.

help me to solved this issue.

Here is my log.

twitter connection code. http://www.androidhive.info/2012/09/android-twitter-oauth-connect-tutorial/ this is a develop

Answer 1

To my knowledge nothing much has changed with the OAuth implementation that would cause this, however, after you have authenticated using OAuth if you were then using non-SSL requests for data this may have worked previously but would not now. Twitter introduced a change restricting access to SSL/TLS connections only on January 14th 2014.

Somewhere in your Java code there will be URL's that are being used to retrieve data from Twitter's servers. I would suggest you do a search/replace through your code, where for any occurrences of http://api.twitter.com/ you replace them with https://api.twitter.com/ and this may hopefully solve this issue. It's possible there are other issues that may come to light afterwards but at least this is your first step.

By specifying https this makes sure you are using SSL protocol to ensure data is kept secure during transmission between your application and Twitter.

If you need more information to optionally validate and verify the SSL certificate in your code for additional security, then read Connecting to Twitter API via SSL on Twitter's developers documentation website.

Edit: Just to clarify further, in order to receive this error message you must have successfully authenticated using OAuth via an SSL URL, but then reverted to non-SSL URL's for follow-on data requests.

If you're using sign-post + Twitter4j, you'd define your OAuth providers as follows:

private DefaultOAuthConsumer mOAuthConsumer = null;
private DefaultOAuthProvider httpOauthprovider = new DefaultOAuthProvider("https://api.twitter.com/oauth/request_token",
        "https://api.twitter.com/oauth/access_token",
        "https://api.twitter.com/oauth/authorize");

then perform user authentication:

private void getTwitterAuthorisation() {
    if (backend.hasNetworkConnection(this, true)) {
        new Thread(new Runnable() {
            public void run() {
                try {
                    mOAuthConsumer = newOAuthConsumer();
                    String authUrl = httpOauthprovider.retrieveRequestToken(mOAuthConsumer, CALLBACK);
                    startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(authUrl)));
                } catch (Exception e) {
                    Log.e(TAG, "getTwitterAuthorisation()", e);
                }
            }
        }).start();
    }
}

then obtain the tokens:

TwitterCredentials creds = null;
            try {
                httpOauthprovider.retrieveAccessToken(mOAuthConsumer, verifier);
                final String token = mOAuthConsumer.getToken();
                final String secret = mOAuthConsumer.getTokenSecret();
                final AccessToken accessToken = new AccessToken(token, secret);
                final Twitter twitter = TwitterFactory.getSingleton();
                twitter.setOAuthConsumer(mOAuthConsumer.getConsumerKey(), mOAuthConsumer.getConsumerSecret());
                twitter.setOAuthAccessToken(accessToken);
                final long twitterId = twitter.getId();
                final String twitterScreenName = twitter.getScreenName();
                creds = new TwitterCredentials();
                creds.oauthToken = token;
                creds.oauthSecret = secret;
                creds.twitterId = twitterId;
                creds.screenName = twitterScreenName;
            } catch (Exception e) {
                Log.e(TAG, "doTwitterConnect", e);
            }
            return creds;
